PATENT l CHARLES V. HENKEL, OF NEW YORK, N. Y.

TEMPORARY BINDER.

SPECIFICATION forming part of Letters Patent No. 665,740, dated January 8, 1901.

Application filed September 22, 1900. Serial No. 30,752. (No model.)

T0 all whom t may con/cern:

Be it known that I, CHARLES V. HENKEL,

of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Temporary Binder, of which the following is a full, clear, and exact description.

The purpose of this invention is to provide a temporary binder which may readily be adj usted to suit the amount of papers t-herein, thus rendering the capacity of the binder variable according to the number of papers it is desired to bind or file.

This specification is the disclosure of one form of my invention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a rear elevation of the binder, the covers being thrown open. Fig. 2 is a sectional view taken through one of the sectional posts. Fig. 3 is a detail perspective View of one of the sections of the posts. Fig. et is a similar view of one of the end sections Which are permanently fastened to the back of the binder. Fig. 5 is a cross-section taken on the line 5 5 of Fig. 2. Fig. 6 is a similar view taken on the line 6 6 of Fig. 2. Fig. 7 is a sectional view showing a slightlymodiiied form of the invention. Fig. 8 is a sectional View taken on the line 8 8 of Fig. 7, and Fig. 9 is a fragmentary plan View of the auxiliary back-section which is used in the modifications illustrated in Figs. 7 and 8.

Referring to Figs. l to 6, a represents the back-sections of the binder, and bthe covers, which are carried, respectively, on the backs by a iexible connection of the usual sort. The backs a are rigidly connected with each other by the sectional filing-posts, which are preferably two in number (see Fig. l) and each of which comprises a stationary end section c and a stationary end section CZ, said end sections being permanently attached, re-

Each filing-post also comprises one or more intermediate sections e.

The end section c is tubular in form and is open at its inner end. This end portion is formed with indentations c', which are diametrically opposite each other and which forni slight projections on the inner surface of the section. Theintermediatesectioneisformed with a tubular portion e and a reduced portion e2 at one end. This reduced portion e2 is formed with oppositely-disposed longitudinal grooves es therein. (See Figs. 3 and 6.) The part e2-of the section e is adapted to be inserted into the section c, so that the projections formed by the indentations c will slide in the grooves e3. The reduced portion e2 is further provided with short transverse grooves e4, which are four in number, corresponding to the indentations c and which are arranged in pairs respectively leading to the grooves e3. Therefore when the part e2 is inserted in the section c it is first moved axially until the inner end of the part e of the intermediate section strikes against the inner end of the section c, whereupon the transverse groove e4 will register with the indentations c', and then by turning the intermediate section e the projections formed by the indentations c will be engaged with the walls of the grooves e4, thus locking the two sections c and e together. If desired, the grooves e4 may be formed with a slight spiral disposition with respect-to the axis of the section e, so that when the section e is turned it will be locked in place much in the nature of a screw. Y I

The part e of the intermediate section eis formed exactly the same as the inner part of the end section c, so that it may be connected with thev part e2 of a second intermediate section, if desired, and so the several sections may be built u p, one on the other, to increase the length of the iiling-posts. Each lingpost therefore comprises two stationary end sections and as many intermediate sections as are desired.

The end section d is adapted to be locked in the part e of the intermediate section e, which occurs immediately adjacent thereto, and this end section d is tubular in form and has its inner part split, as indicated at d. The inner end ofthe end section cl is formed with tapered portions cl2, as is shown best in Fig. 2, and working within the section CZ is a screw f, the inner end f of which is formed conical to work with the tapered portions d2 of the section d. When, therefore, the screw IOO f is moved inward to the position indicated in Fig. 2, the end f ofthe screw will bear against the tapered portions d2 of the section d and will spread the split inner end of the section d, thus binding it against the inner surface of the adjacent section e and looking said section with the section d. The indentations of the part 'e' of the section e, which are similar to the indentations c" of the section c, engage in the slits d of the section d, the same as the indentations c engage in the grooves e3 of the part e2 of the intermediate section e. The screw f is inserted into the section d from the outside of the adjacent back-section a of the binder, and any suitable wrench may be provided for the operation of the screw, also for the purpose of manipulating the intermediate sections e. The parts e' of these sections may be formed with recesses or kerfs e5 to facilitate the engagement of an instrument by which to turn the intermediate sections in and out of their locked positions.

In Figs. l to 6 the screwfhas its end portion visible outside of the back-section a, to which it is attached. In Figs. '7, 8, and 9 I have shown a modified construction which enables me to hide this screw and to give the binder an unbroken and finished appearance, the same as that of a well-bound book. This is effected by means of an auxiliary back-section a', to which the end section d of the filingpost is attached, the same as shown in Fig. 2. This auxiliary back-section a' Works with a back-section a, which is similar to the backsections in Figs. 1 and 2. The other backsection a, which is adjacent to the auxiliary back-section a', is connected with the iirstnamed back-section by a binder c of leather or other flexible material, in which is embodied a spring h. The back a, which is adjacent to the auxiliary back a', is provided with two catchest', adapted to engage in slots 0.3, formed in the ends ot` the auxiliary back a', so as to hold the auxiliary backs snugly against the adjacent back-section a, and thus cause these two parts to operate as one,asillus trated in Fig. -8. The catches t' are mounted to turn in the back,and by turning the catches one way or another they may be engaged with or disengaged from the auxiliary back.

Fig. 7 shows the catches?.` disengaged from the auxiliary back a'. In using this form of the device to adjust the filing-posts it is necessary to release the catches t' and throw open the back of the book, so that access may be had to the screws f. The spring hadjusts itself to the movement of the back-sections ct and always gives the back of the book a symmetrical appearance.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A temporary binder having a filing-post made up of stationary end sections and removable intermediate section or sections, the intermediate sections comprising each a tub ular part and a reduced part at the other end, the tubular parts having projections formed on their inner faces and the reduced parts having grooves therein, for the purpose specified.

2. The intermediate section of a sectional "filing-post in temporary binders, comprising a tubular part at one end and a reduced part at the other end, the tubular part having one or more projections on its inner face, and the reduced part having slots disposed longitudinally and transversely for the purpose specified.

3. Atelnporary binder having two back-sections, a spring connection between the backsections, such connection forming the back of the binder, an auxiliary back-section, a sectional tiling-post extended between the auxiliary back-sections and one of the firstnamed sections, and a catch for removably connecting the auxiliary back-section with the other of the first-named back-sections.

4:. A temporary binder having back-sections, an auxiliary back-section, a removable ling-post extending between the auxiliary back-section and one of the first-named backsections, and a releasable catch for connecting the auxiliary back-section with the other first-named back-section.

5. A temporary binder, having two backsections, an auxiliary back-section, an ad Witnesses:
